If you don’t want to visit Halifax in April, then you should wait until May to fly from Australia, when ticket prices are also cheap, with an average price of $1,335.
The cheapest day to depart on your flight to Halifax is on a Tuesday when prices can be found for as low as $1,502. This is often the case because there is less demand to fly during this day of the week. On the other hand, Sunday is the most expensive day to depart from Australia because it is more convenient for both business and leisure travellers. As a result, prices tend to be around $2,106.
